Green invaders are taking over America. Not invaders from space, but plants! You might not think of plants as dangerous, but in this case they are threatening nature’s delicate food chain.
The invaders are plants brought here from other countries to make gardens and yards look pretty. Ever since people started to arrive on America’s shores, they have carried along trees, flowers, and vegetables from other places. Now there are so many of those plants, they are crowding out the native plants that have lived here since before human settlers arrived.
And that’s a problem, says Dr. Doug Tallamy. He’s insect expert at the University of Delaware. He explains that almost all the plant-eating insects in the United States are specialized, which means they eat only certain plants. Monarch butterfly caterpillars(幼虫),for example, dine on milkweed. If people cut down milkweed and replace it with another plant, the butterflies will not have the food source that they need to survive.
But the trouble doesn’t stop there. When insects can’t get the right plants to eat and they die off, then the birds don’t have enough bugs for their meals. Tallamy points out that almost all migrating birds depend on insets to feed their young.
“We cannot let the plants and animals around us disappear.” says Tallamy, “The way to preserve them is to give them food to eat. But when we plant non-native plants, we are clobbering the food chain, because then we don’t have the insects the birds need to live.”
Fewer of the right plants mean fewer bugs, and fewer bugs mean fewer birds. And that’s bad for the Earth, because we need a variety of living things to keep the planet healthy and beautiful.
The good news is, garden centers sell native plants. “Just Google ‘native plants’ and your location, and you can find out which plants really belong where you live,” says TallamyHow did green invades arrive at America?
| A．They fell down from space. |
| B．They floated to the America’s shores. |
| C．They were brought in from foreign countries |
| D．They has lived here since human settlers arrived |

| A．Almost all the plant-eating insects in a place eat certain plants. |
| B．Monarch butterfly caterpillars can’t survive without milkweed. |
| C．If insects can’t eat the right plants, they will find another one. |

If you’re a male and you’re reading this, congratulations! You’re a survivor. According to statistics，you’re more than twice as likely to die of skin cancer than a woman，and nine times more likely to die of AIDS. Assuming you make it to the end of your natural term，about 78 years for men in Australia，you’ll die on average five years before a woman.
There're many reasons for this--typically，men take more risks than women and are more likely to drink and smoke but perhaps more importantly, men don’t go to the doctor.
“Men aren't seeing doctors as often as they should，” says Dr. Gullotta.“This is particularly so
for the over-40s, when diseases tend to strike. According to a recent survey, 95％of women aged between 15 and early 49s see a doctor once a year, compared to 70％of men in the same age group.
“A lot of men think they’re unbeatable，”Gullotta says．“They only come in when a friend drops dead on the golf course and they think, Geez, if it could happen to him …”
Then there’s the ostrich（鸵鸟）approach．“Some men are scared of what might be there and would rather not know,” says Dr. Ross Cartmill.
“Most men get their cars serviced more regularly than they service their bodies,” Cartmill says. He believes most diseases that commonly affect men could be addressed by preventive check-ups.
“Prevention is cheaper in the long run than having to treat the diseases．Besides, the final cost is far greater，it’s called premature death.”Why does the author congratulate male readers at the beginning of the passage?
| A．They can live longer than they expected． |
| B．They are sure to enjoy a longer and happier life. |
| C．They have lived long enough to read this article. |
| D．They are more likely to survive serious diseases now． |
Which of the author’s statements is the most important reason that men die five years earlier on average than women according to the passage?
| A．Men drink and smoke much more than women. |
| B．Men don’t seek medical care as often as women. |
| C．Men are more likely to suffer from deadly diseases. |
| D．Men aren’t as cautious as women in face of danger. |
Which of the following best completes the underlined sentence “Geez, if it could happen to him…” （in Para 4） ?
| A．it could happen to me，too. |
| B．it would be a big misfortune. |
| C．I should avoid playing golf. |
| D．I should consider myself lucky. |
What does Dr．Ross Cartmill mean by“the ostrich approach”（in Para 5）?
| A．A casual attitude towards one’s health conditions. |
| B．A new treatment for certain psychological problems． |
| C．Refusal to get medical treatment for fear of the pain involved. |
| D．Unwillingness to find out about one’s disease because of fear. |

It was a Sunday morning, and I was in a terrible mood. Two of my friends had gone to the movies the night before and hadn’t invited me．I was in my room thinking of ways to make them sorry when my father came in. “Want to go for a ride，today，Beck? It’s a beautiful day.”
“No ! Leave me alone!”Those were the last words I said to him that morning．
My friends called and invited me to go to the mall with them a few hours later．I forgot to be mad at them and went. I came home to find a note on the table. My mother put it where I would be sure to see it. “Dad has had an accident. Please meet us at Highland Park Hospital”．
When I reached the hospital，my mother came out and told me my father’s injuries were extensive（大量）. “Your father told the driver to leave him alone and just call 911，thank God! If he had moved Daddy，there’s no telling what might have happened．A broken rib（肋骨）might have pierced（穿透）a lung….”
My mother may have said more，but I didn’t hear．I didn’t hear anything except those terrible
words：Leave me alone．My dad said them to save himself from being hurt more．How much had I hurt him when I hurled(猛投) those words at him earlier in the day?
It was several days later that he was finally able to have a conversation．I held his hand gently, afraid of hurting him．
“Daddy… I am so sorry….”
“It’s okay，sweetheart．I'll be okay．”
“No，”I said，“I mean about what I said to you that day．You know, that morning?”
My father could no more tell a lie than he could fly．He looked at me and said．“Sweetheart,
I don’t remember anything about that day，not before，during or after the accident.I remember kissing you good night the night before，though．”He managed a weak smile．

can heal．And we all have the power to choose our words. I intend to do that very carefully from now on.The author was in bad mood that morning because ________.

When the first spring flowers blossom, Easter comes. It is the oldest Christian feast, in memory of the resurrection (复活) of Jesus Christ.
Along with the traditional Easter walk or outing, the giving of Easter eggs and, more recently, of Easter presents is a main feature of the feast. Parents give their children “Easter eggs” – colored and boiled eggs, chocolate eggs, marzipan eggs – Easter bunnies, sweets, and other gifts. In some German regions, children virtually “collect” Easter eggs from their relatives, especially their godparents.
Usually, the Easter eggs are carefully hidden in the garden or in the house and the children must search for them on the morning of the Sunday. They are told that the Easter bunny has brought them. This anonymous(匿名的), mysterious bunny is like Santa Claus at Christmas. But it is less of an “educational” figure than Santa Claus is, since the eggs are not given to children as rewards for being good.
Some Easter egg games have been preserved at certain places in Germany or have even been newly developed. Children try to outdo others in rolling colored eggs down grassy slopes, for instance, or they knock the eggs’ pointed ends together and the child whose egg does not shatter（砸碎） gets the broken one, too. In some places, this custom was even used as the name of local festival. What are the main features of Easter?
| A．Easter walk, Easter eggs, Easter bunnies and sweets. |
| B．Easter outing and the giving of Easter presents. |
| C．Easter walk, Easter eggs, Easter bunnies and Easter egg games. |
| D．Easter outing, the collecting of Easter eggs, and Easter games |
The underlined word “outdo” means ________.
| A．do better than | B．do worse than | C．do slower than | D．do the same as |
What can be inferred from the passage?
E.Easter bunny will give gifts to children for better or worse.
F.Easter bunny is very similar to Santa Claus, as they both bring gifts to children.
G.Easter always falls on a Sunday.
H.Some of the local festivals are named by Easter egg games.
